I have an HH Expedition Zip, but I don't use it much anymore for a couple of reasons:
1) It's reasonably comfortable, but is not in the same comfort class as a 10 to 11 ft. hammock. Not even close.
2) I despise built-in bugnets - makes me feel like a prisoner zipped up in there. You wanna get out of your hammock fast because of a leg cramp, a bladder about to burst, or an approaching critter? An independent bottom-entry, or TED-style bugnet, is a much easier escape.
3) I do most of my camping in non-mosquito weather. It drives me nuts carrying a bugnet when there are no bugs.
